Motor-driven vehicle and its card key device

摘要

Object : To facilitate unlocking a battery lock and a parking lock on a rental motor-driven vehicle. Solving Means : An ID card (2) storing ID information and issued by a central management apparatus (1) is read by a reception station (5), which carries out a predetermined renting process to write permission information into the ID card (2). The ID card (2) is inserted into a card reader on a motor-assisted bicycle (7) to check the ID information, so that the parking lock can electrically be unlocked. After the motor-assisted bicycle has run, a battery is removed from the bicycle using the ID card (2) which stores a battery ID and vehicle information, and exchanged for a charged battery stored in a battery exchanger (8). The charged battery is installed on the bicycle, which is then returned to a parking lot (6).
